Application filed October 6, 1910. Serial No. 585,632.

Be it known that 1, PAUL Pnrmr, a subject of the King of Saxony,residing at '13 Lindenstrasse, Heidenheim onthe Brenz,

Germany, have invented certain new and useful Improvements inPaper-Making Machines; and I do hereby declare the following to beafull, clear, and exact description of the invention.

This invention has for its object an arrangement in longitudinalstraining cloth paper-making machines, which enables the .cloth to beadjusted to various inclinations,

without the height of ,the' breast-roll end of the cloth being therebyaltered.

Several forms of construction of the improved arrangement are shown inthe accompanying drawings, in which v Figure 1 is a side elevation of apaper making machine embodying my invention. Figs. 2, 3, 4, and 5 aresimilar views of machines of modified construction.

In the machine illustrated in Fig. 1 only the inclination of theshake-frame a is variable, while the inclination of the suction part bremain-s constant. The standards Z of the suction part are made so as tobe telescopically extensible. Toothed wheels g, I which are operated bymeans of a crank in,

a shaft and pairs of bevel wheels, engage with rack-bars (not shown),which? are firmly connected with the displaceable hoodshaped upper partsof the standards 1 in such away, that by rotating the crank 70,

the suction part is raised vertically parallel with itself. An arm h iscast on each of the two right hand standards. The ends of the rails orgirders 0 are pivoted to these two arms 71, which girders are pivotal onbolts e and carry by the intermediary of standards p and f the bars ofthe shakeframe; the standard or bracket 1 is pivoted in the ordinaryway, so that it allows of the necessary shaking movement of the cloth.By vertically displacing the suction part, the inclination of theshake-frame is altered.

' The suction part is given such an inclination that when theshake-frame is adjusted to the most inclined position which it may bedesired to give it while the machine is in operation, the part of thecloth lying on the shake-frame and that lying on the suction frame areapproximately in-the same direction and lie in one plane. If the suctionpart were tolie at a lesser inclination or horizontally when theshake-frame was confrom the first suction boxes and from the lastrollers of the shake-frame. Fig. 1 showsthe machine with the shake-frameadjusted to the greatest inclination, while the position of the clothwhen the make-frame.

is lying horizontally is shown in dotted lines in F i 1.

In the form of construction shown in Fig. 2 the standards Z carryingboth the .ends of the girders adjacent 'to the squeezing press areconnected to-the lower end of a screwed spindle q vertically mounted ina standard 'm, the upper end of which screwed spindle is formed as aworm-wheel n. By turning the crank g the worm wheel 72. is rotated andthereby the spindle q raised and the inclination of the cloth altered.

In the form of constructionshown in Fig.

8 the pair of girders c is arranged above the straining cloth. Thesuction part is carried by standards Z rigidly mounted on the girders.The shakeframe a? is suspended from the girders by means of flexiblesteel bands 72?, which allow of the necessary shaking motion. 1

In the forms of construction shown in Figs. 4 and5, the rollers of theshake-frame and the suction boxes are supported by a single continuouspair of rails s, which in. Fig. lare stiffened by struts 14,0, w and in5'by a truss frame a, o, w, in such a waythat the flexion load may befreely carried by the rails and the arrangement of standards (pandZof-Fig. 1) is superfluous.

In the form of construction shown in Fig. 5, the breast-roll end of thepair of rails is suspended on two pillars or standards f of purpose thatbecause of the breast-roll end of the shake-frame not being displaced inheight when the inclination of the cloth or apron is changed, the flowof paper pulp on PatentedDee. 13, 1910.; I

siderably inclined, the cloth in consequence of the tension imparted toit would tend to I adjust itself in a straight line and lift away thecloth is in no way afl'ected by changing the inclination so that theinclination of the cloth may be altered within wide limits even duringthe working, and thus, without the slightest loss of time, theinclination of the cloth, which at the moment appears to be the mostsuitable one, may be ascertained by testing during the working of'themachine, which is impossible in the ordinary apparatus .in which, whenthe inclination'of the cloth .is altered, the os'ition of the breastrollend of the shake-. ame is also altered in height.

clined suction frame a normally inclined shake frame, a sub-frameextending from the breast roller end of the shake frame to the front endof the suction frame, said subframe being pivotally mounted at thebreast roller end of the shake frame, means connecting with the suctionframe for raising or lowering the endof the shake frame next to thesuction frame, together with the whole suction frame, the plane of thetwo frames,

including in no position an angle of less than 180.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
